Apparently, launch of AMD's Radeon HD 8800 series is close enough for some sources to come up with specifications. The HD 8800 series, according to one source, is based on a new silicon codenamed "Oland," which is built on the 28 nm process, packing 3.4 billion transistors with around 270 mm² die-area. According to the source, the two HD 8800 series models, the HD 8870 "Oland XT" will up performance per Watt and cost-performance ratios over current HD 7800 series, while maintaining current process technologies.

Likely because AMD had performance leads at times, well before nVidia got more of Kepler out. If you are a top dog you don't have much of a reason to lower prices. People will pay for it. If 8000 series is seeing a price drop that big then it makes me suspect performance won't beat nVidia in the end so AMD goes back to competing based on price. Which is good cause maybe it'll get nVidia to lower some as well.

I don't see this pricing to be accurate. Unless they are going back to the AMD/ATI GPU pricing ways.

hah, i bet somebodys gonna make a 8888 in asia...
for the ones who dont know, 8 means "rich" in chinese, so people here spend lots of money on car license plates with as many 8s in them as possible, and WD sold an 888GB HDD a while ago if i remember correctly :D

I am still waiting for the 7990 :p

Jokes aside, I was pretty set on a couple 7970s toxic but if specs are already coming out I guess I'll wait :)

If 8870 can perform better than a 7970 at 279 bucks, it's a big fuckin win. :D

I hope they don't drop the balls (Support) on their HD 5*** series, My HD 5850 is still fast enough and serving in my secondary system.

Seems weird that the transistor density is lower with the supposed new part (13.2million/mm^2 w/Pitcairn as opposed to 12.59million/mm^2 w/ Swedish island).

If the number are correct - and it looks like someones guesstimate rather than hard numbers- then it's a 112 TMU, 32 ROP part with 2000+ shaders.
Not sure how they arrive at their SP/DP flop numbers unless they are actuals by some measurement. I was under the impression that theoretical FLOP's were measured by- HD 7870 for example:
Core speed * shader count * 2 primatives/clock...which would be 2.56TFLOPS SP, with double precision at 1/16 rate =160GFLOPS

Wow, the increase in GFLOPS per watt is enormous for something on the same process:

2.25TFlops with 175Watt results in ~12.9GFlops/Watt for the 7870 while the 8870 has:
3.94TFlops with 160Watts powerdraw resulting in 24.6 GFlops/Watt.

Thats practically doubling the Flops/W rating on the same process O.O.

I wonder what breaktrough made that possible.

I think the drivers for those cards are tweaked enough already.

Correct, but i was talking about the new games, HD58** series has enough to play atleast 1 more year's future games (Exceptional are there but still)

8870:
1792 * 2 * 1.1 GHz = 3,942.4 GFlops/3.9424 TFlops
You got the 112 TMUs and 32 ROPs right.

8850:
1536 * 2 * 0.975 GHz = 2,995.2 GFlops/2.9952 TFlops
96 TMUs and 32 ROPs

8870/8850 = Lower end Tahiti

8850 = 7930 "Tahiti LE" rebranded as Oland Pro
8870 = 7950 "Tahiti Pro" rebranded as Oland XT

Oland dies are probably just 64 GCN * 28 clusters rather than 32 clusters*. With the Venus dies being 80 GCN v2 * 32 clusters for 2,560 GCN cores for Venus XT and 1920-2240 for Venus Pro.

*or similar 128 * 14 / 12

I AM OVER THE MOON TO HEAR ABOUT THESE NEW 8xxx GPUs!!!! as i need to replace my 6970s

Sadly, Me no likey AMDs drivers so i wont be buying another AMD GPU till they sort that out.
Just waiting to see what Nvidia comes out otherwise 2 670s in SLi scale exceptionally well!

8870:
1792 * 2 * 1.1 GHz = 3,942.4 GFlops/3.9424 TFlops
You got the 112 TMUs and 32 ROPs right.
The head scratcher was the comparison between the 7870 and the 8870.

HD 7870 = 1280 * 2 * 1 GHz = 2560 GFlops/2.56 TFlops (as per my original post)- correct?
Yet the graph states 2.25 TFlops :confused:

So I was wondering if the 2.25TF calc for the HD 7870 was also a factor in the 3.94 TF for the new card (i.e. 12%* lower than theoretical). If the Oland is a 1792 shader part, then whomever put the graph together has trouble multiplying three numbers together it would seem...since 3.94TF is a theoretical number, and therefore the theoretical number for the 7870 is 2.56TF - not 2.25

* 1792 shaders * 1.12 = ......... -Which was where the 2k number came in.

Hey look its AMD with the 28nm-HP process like NVidia does with the 600-series.
I think the actual 7000-Series is completely at the the performance-lowpower 28nm-HPL process.
That could be a reason why the OC on the 7000-series runs earlier to high leakage than NVidia does.
